RAILROAD-TIE PLATE.

SPECIFICATION forming part of Letters Patent No. 612,752, dated October18, 1898.

Application fled April 18, 1898.

To @ZZ whom it may concern:

Beit known that I, SIMON D. S. N Annan, of Le Grand, in the county ofMarshall and State of Iowa, have invented a new and useful Improvementin Railroad-Tie Plates, of which the following is a specification.

My invention is in the nature of an im provement upon the metallicrailroad-tie for which Letters Patent, No. 594,410, were grant ed meNovember 30, 1897 and it consists in the improved means for fasteningthe rails down upon the tie in a manner at once secure and easilyapplied and removed, as will be hereinafterfully described.

Figure 1 is a perspective view of the railroad-tie with the' tie-plateand rails applied to the same. Fig. 2 is a view of the railroadtie withthe top plate removed, and Fig. 3 is an enlarged vertical section takenthrough the tie-plate at right angles to the rail.

In the drawings, 1 is the top plate; 2, the bottom plate; 3 3, the endplates, and 5 the interposed series of cells or compartments forming myiron railroad-tie, as shown and described in my previous patent referredto.

Upon the top of plate 1, Where the rails rest, there are disposedbase-plates 6, which are thicker in the middle than at their edges andWhose relatively thin edges are bolted down or otherwise secured to thetop plate 1 of the tie. In the middle of each one of these plates (5, onthe under side and in a line at right angles to the rail, there is agroove or channel (see Fig. 3) adapted to receive one of the branches yofthe forked clamp-bolt 4, the other branch o: resting abovethe bottomiiange of the rail. The outer ends of these clamp-bolts 4 are securedfirmly to the railroad-tie eithe'r by a horizontal bolt in a clip 8,fastened to the tie, as shown, or by any other convenient means. For thetwo rails there need be only three of these clamp-bolts 4, for a rigidoverlapping iiange-plate 7 is arranged at one end of the tie of the samegeneral character as those used in my previous patent.

To remove the rails or disconnect the tie therefrom, it is onlynecessary to loosen the bolts in the ends of the clamp-bolts 4 and thenslide theseclamp-bolts longitudinally away from the rails until theirforked ends 0c and fy are disconnected from the base of the rails, andthe tie may then be moved lon Serial No. 677,997. (No model.)

gitudinally to the right of Fig. 1, which takes the flange-plate 7 awayfrom the rail.

Vhen the rails are in place on their baseplates 6 and the latter bolteddown to the tie,

it will be seen that the clamp-bolts 4 lock the rail down to thebase-plate by reason of the fact that one prong, is above therail-flange Vand the other prong,`y, is underneath the rigid base-plate6.

In laying a track theties, with their stationary flange-plates 7, arealternated, so that the'iiange-plate 7 of one tie is on one side of thetrack and ,the iiange-plate 7 of the next tie is on the other side ofthe track, which makes a stiffer trackas against lateral displacement.

In constructing the casing 5 with the diamond-shaped cells orcompartments, I prefer to make it of malleable iron, one-half inch inthickness, and the balance of the tie ispreferably made of Swedish ironone-half inch in thickness and galvanized.

I-Iaving thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A railroad-tie plate consisting of a base-v `securing them to the tiesubstantially as shown and described.

. 2. A railroad-tie plate consisting of a base-` .plate having arelatively thick portion and thin edges and a locking groove or recesson `the under side transversely to the rail and opening at its edges,clamp-bolts with forked inner ends lying wholly above the tie adaptedtoembrace both a part-of the base-plate and the base-,flange of therail, and means for fas `tening the clamp-bolts to the tie substantiallyas shown, and described.
